The book ABigFatCrisis: TheHiddenForcesBehindObesityEpidemic— andHowWeCanEndIt by Deborah Cohen, a senior natural scientist, is very popular now. {#blank#}1{#/blank#} But according to this book, the following are some misunderstandings of obesity or being overweight.

1)．If you're obese, blame your genes.

    {#blank#}2{#/blank#} Yet, between 1980 and 2000, the number of Americans who are obese has doubled—too quickly for genetic factors to be responsible. At restaurants, a dollar puts more calories on our plates than ever before, because restaurant meals usually have more calories than what we prepare at home, so people who eat out more frequently have higher rates of obesity than those who eat out less.

2)．If you're obese, you lack self­control.

    Research shows that if we are faced with too much information, we have a tendency to make poor choices on diet. {#blank#}3{#/blank#} Even, the most vigilant(警觉的)people may not be good controllers of themselves.

3)．{#blank#}4{#/blank#}

    Although the US Department of Agriculture estimates that fewer than 5 per cent of Americans live in the “food deserts”， about 65 per cent of the nation's population is obese. For most of us, obesity is not related to access to more fresh fruits and vegetables, but to the choices we make in supermarkets.

4)．The problem is not that we eat too much, but that we don't exercise.

    Michelle Obama's “Let's Move” campaign is based on the idea that if kids exercise more, childhood obesity rates will decrease. {#blank#}5{#/blank#} In fact, although a drop in work­related physical activity may explain up to 100 fewer calories burned, leisure physical activity appears to have increased.

How Can I Fight Laziness?

    Lazy people will never amount to anything in life. However, laziness can be defeated once a few changes have been made in your mind.

    {#blank#}1{#/blank#}. Many people lack sleep constantly, since they stay up too late and get up too early to prepare for work. These people have little motivation once they arrive home. Laziness works hand in hand with a lack of motivation and a tendency to put off things. By adjusting your sleep schedule to provide a few more hours of meaningful rest, you can fight laziness throughout the day.

    Another way to fight laziness is to change your mind from passive to active. Some people treat their lives as if they were pushed from task to task. Others take a more proactive（主动的） approach, viewing each task as a challenge they must overcome alone. {#blank#}2{#/blank#}

    Some people fight laziness by removing the temptations(诱惑) that surround them. A television in the living room may provide entertainment, but watching too much TV often contributes to laziness. {#blank#}3{#/blank#} Complete a few tasks and reward yourself with what you enjoy, such as a good dinner or a film.

    Laziness can also be a lasting problem at home. Couples and children may all have different energy levels, but laziness can be spread if not dealt with immediately. {#blank#}4{#/blank#} Be the first to collect and wash dishes after a meal. Others in the home may eventually follow your example and perform their own task. It is difficult to practice laziness when you are surrounded by motivated people.

    {#blank#}5{#/blank#} Enough exercise and a balanced diet can help you to develop a healthy lifestyle, thus enabling you to have more energy and help lift your spirits.

A．To fight family laziness, set an example.

B．One way to fight laziness is to get enough sleep.

C．Knowing how to fight laziness is important.

D．Finally, taking exercise regularly can help you fight laziness.

E. With strong determination, you will be able to achieve your goal.

F. Create a reward system for yourself, just as parents do for a child.

G. Laziness sets in when you no longer feel in charge of your own life.

    Eyesight plays a very important role in our daily life. Every waking moment, the eyes are working to see the world around us. Over forty percent of Americans worry about losing eyesight, but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight:

    Schedule yearly exams. {#blank#}1{#/blank#}Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eyeglasses.

    Protect against UV rays (紫外线). Long-term stay in the sun creates risk to your eyes. No matter what the season is, it's extremely important to wear sunglasses. {#blank#}2{#/blank#}

    {#blank#}3{#/blank#}Two-thirds of Americans spend up to seven hours a day using computers or other digital (数字的)products.   This frequent eye activity increases the risk for eye tiredness.

    {#blank#}4{#/blank#} As part of a healthy diet, eat more fruits and vegetables each day. Vitamins C and E help protect eyesight and promote eye health.

    Practice safe wear and care of contact lenses (隐形眼镜). Many Americans use contact lenses to improve their eyesight. While some follow the medical guidance for wearing contact lenses, many are breaking the rules and putting their eyesight at risk. {#blank#}5{#/blank#} Otherwise, you may have problems such as red eyes, pain in the eyes, or a more serious condition.

    What will you do if you can't eat everything bought in the canteen? {#blank#}1{#/blank#} According to a survey, what students waste every year could feed over 10 million people.

    {#blank#}2{#/blank#} According to Xinhua News Agency, the food wasted by Chinese people is about 50 million tons of grain every year, which could feed 200 million people.

    Food waste, which has become a global issue, serves as a mirror that reflects various cultural and social issues in different countries. In the West, for instance, consumerism, the belief that it's a good thing to use a lot of goods and services, is often to blame for food waste. {#blank#}3{#/blank#} Chinese people are well known for being hospitable and generous. Many even feel that they lose face if their guests have eaten all the food. On campus, a generation of single children is less aware of the food waste issue. Students nowadays are well protected by their families and hardly have any concept of how much toil others go through in order to provide them with the food they eat.

    {#blank#}4{#/blank#} There are over 925 million hungry people in the world, most of whom live in underdeveloped countries and areas. They don't have enough food to eat. Many children die for lack of nutrition each year in some African countries. And farmers work very hard to grow the crops. {#blank#}5{#/blank#} It's also important that everyone should think about how they can do their bit to reduce food waste.

A. Students' waste is extremely serious.

B. China, in turn, features its own eating culture.

C. But canteen waste is extremely the tip of the iceberg.

D. Students can never realize the serious food crisis.

E. Compared with them, some live in a different world.

F. So there's no excuse that we should waste our food.

G. Most of us would simply throw away any leftover food.
